LOS ANGELES, April 17 (Xinhua) -- Global warming will melt all the ice in the Arctic Ocean every summer, raising earth temperatures even further, researchers at the University of California-Los Angeles (UCLA) warned.
The findings, available online Sunday in the April issue of Earth and Planetary Science Letters, a leading journal in geoscience, were based on analysis of the fossilized remains of four-million-year-old mollusks, they said.
Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today, the researchers said.
And these ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months, according to the researchers.
Such balmy polar weather would certainly melt all the ice in the Arctic Ocean every summer, said Aradhna Tripani, an assistant professor at the UCLA's departments of Earth and space sciences.
"Our data from the early Pliocene, when carbon dioxide levels remained close to modern levels for thousands of years, may indicate how warm the planet will eventually become if carbon dioxide levels are stabilized at the current value of 400 parts per million," she said.
The earth's temperature was raised five to nine degrees Fahrenheit merely by the absence of year-round Arctic ice, according to Tripani.
The results of the study lend support to assertions made by climate modelers that summertime sea ice may be eliminated in the next 50 to 100 years, which would have far-reaching consequences for Earth's climate, she said.
"The Intergovernmental Panel on Climate Change identifies the early Pliocene as the best geological analog for climate change in the 21st century and beyond," said Tripati. "The climate-modeling community hopes to use the early Pliocene as a benchmark for testing models used for forecasting future climate change."

Climate modelers, BWAHAHAHAHA...
We’re all going to die Ping!
They say that as if that were a bad thing.
Lol. I’m sick with the flu but this cheered me up. Let’s remember this and drag it out in September;)
WE’RE ALL GOING TO DIE!!
Sound the alarum far and wide. Mollusks are responsible!
US greenhouse gases drop to 15-year low

Greenhouse gas emissions in the US dropped to their lowest level in 15 years in 2009 as the impact of the financial crisis led to decreases in fuel and electricity consumption, according to newly published figures.
In 2009, the US saw its emissions of the six main greenhouses gases drop 6 per cent year-on-year to 6,633m metric tonnes, the lowest total since 1995. Despite that annual fall, emissions rose by more than 7.3 per cent between 1990 and 2009.
The figures, released by the Environmental Protection Agency, are likely to be seized upon by Republicans as evidence that there is no need for further regulation of carbon emissions. The GOP has embarked on a campaign in recent months to strip the EPA of its ability to regulate hydrocarbons as well as other pollutants.

Those damned SUV’s back in the Pliocene....
If they keep predicting this, eventually they’ll be right.
They’ve been predicting this for several years.
If the Warmists really believed in their spew they would be buying beachfront property in the Antartic right now while it is cheap.
This libtardic crap will never end..
Yes, finally a Northwest passage!
I knew those slimy b@st@rds would be the death of us someday!
Relating this era to the Piocene is......obscene.
Are these people gainfully employed or are they just sucking grants into their voracious maws?
How about that. Since I’m living just south of the Arctic Circle, this means I’ll be able to grow corn, raise chickens, and enjoy shade from maples instead of black spruce and willows.
On the other hand, here in the real world, there’s still about three feet of snow on the ground slowly melting, and it was 8 degrees this morning.
No it won’t
Don’t bother challenging me on this unless you look at my profile and think its a wise idea.

Bu, bu, but, a study by scientists says it's true..../s
LOL
...AND it was on MSNBC.../s
It cost me $3100 dollars last year to heat my house. Global Warming cannot come too fast to suit me.
